Contribution

It provides the first comprehensive microscopic entropy calculations for N=2 extremal black holes, validating the Bekenstein-Hawking entropy in these cases.

Findings

Microscopic entropy matches Bekenstein-Hawking entropy

Results are consistent with the N=2 area formula

Agreement holds across various compactifications

Abstract

String theory is used to compute the microscopic entropy for several examples of black holes in compactifications with $N=2$ supersymmetry. Agreement with the Bekenstein-Hawking entropy and the moduli-independent $N=2$ area formula is found in all cases.
